'Paramedic' Ants Are the First to Rescue and Heal Their Wounded Comrades. Matabele ants nurse each other back to health after battle with a surprisingly high success rate, a new study finds. A new study reveals that after a raid on a termite nest, the injured ants are cared for by their comrades.
When an ant is injured in a fight, it calls its mates for help by excreting a chemical substance which makes them carry their injured comrade back to the nest. Erik T. Frank already described this rescue service in 2017.
In this species, they do not fly. So the only way for the future queen to mate with males is to find a male…. They first mate in their nest with their siblings — their brothers — and then they need to have some genetic diversity, so the carrying is to increase the outbreeding.
A recent study shows that aggressive colonies of army ants can be cooperative when they have to. If the queen of one colony dies, the colony will attempt to assimilate itself into another.
There is a compelling scientific reason behind an ant's attraction to a dead ant. Ants understand death on a sophisticated level. They bring their deceased members away from the hive to a “cemetery.” You might have noticed this a few times if you looked closely at an anthill.
If you kill the ants as they appear, there is no way to reach the rest of the colony. This is why ants keep showing up. You can't just kill the ants you see, we have to take down the whole colony.
Cleaning Up
As well as being a kind of dumpster, the midden also functions as a cemetery. Ants transport their dead there in order to protect themselves and their queen from contamination. This behavior has to do with the way ants communicate with each other via chemicals.
Ants recognize foes and not friends.
Bumping into each other is another way ants correspond. When ants want to alert others about something that could be useful to their colony, they use their antennas to touch or “bump” other ants to pick up their scent. This lets them smell the unique scent of each ant before informing them of their discovery.

As well as communicating via pheromones, sound and touch, ants talk to each other by exchanging liquid mouth-to-mouth in a process called trophallaxis.
Therefore, you should not clean up the dead ants so that you can identify their nest. Have you noticed an indoor ant nest? Tracking or trailing to a nest in your home is very crucial. Their presence in your home means food and water contamination as well as structural damage.
In ants, tandem running is used for social learning, by which one ant leads another native ant from the nest to the food source it has found. Tandem running is also used to find and choose better, new nest sites to which the colony can emigrate.
Ants antennate, or touch each other with their antennae, for a variety of reasons such as to get another ant to move out of the way, to prod a particularly lazy individual into action or to solicit food.
As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
Turns out ants don't really mourn or grieve or even have graveyards for the same reasons we as humans do. It all comes down to chemicals and smells and pheromones.
Ants don't have complex emotions such as love, anger, or empathy, but they do approach things they find pleasant and avoid the unpleasant. They can smell with their antennae, and so follow trails, find food and recognise their own colony.
It's Communication. Talk about intimate communication. Researchers have found that ants pass along chemical signals with their nest mates by sharing saliva.
This behavior is the act of carrying their dead ant colony members from the area. This is done as a way to sanitize the ant nests and keep infection and disease from spreading.
A recent study of ants' sleep cycle found that the average worker ant takes approximately 250 naps each day, with each one lasting just over a minute. That adds up to 4 hours and 48 minutes of sleep per day. The research also found that 80 percent of the ant workforce was awake and active at any one time.
Ants use pheromones in a number of different ways, such as releasing 'danger' pheromones upon death to alert nearby ants, or to create chemical trails from their nest to promising food sources. Other ants in the colony can use their antennas to detect these pheromones and respond accordingly.
Ants fight for many reasons. They may be protecting their nest or food storage from enemies, or they may fight to try to take over the nest and food source of other ants. Ants do not just fight different species of ants. They will also fight their own species when necessary.
Like most social insects, ants need to communicate with each other. If you watch ants on a trail, you will notice that they often touch each other with their antennae (long feelers on the head) when they meet. An ant's antennae are highly sensitive and contain both touch and smell organs.
Army ants have very few means of communication relative to humans. Visually, they can tell night from day and distinguish almost nothing more than that. They can't even form an image of the world around them, relying on their senses of smell and touch for detecting vibrations.
Despite the relative smallness of an ant's brain in comparison to humans, scientists consider the ant to have the largest brain of all insects. Regardless of how ant brains are rated, they can communicate, avoid and fight enemies, search for food, show courtship signals, and use complex navigation over long distances.
